The duo cover all of her classics - as you'd expect in Carpool Karaoke; they were hardly going to do paint-by-numbers. They pair sang the likes of 'Chandelier'... Kudos to James for attempting those high notes. You get an A for trying, buster!

Of course Sia and James had to belt out Rihanna's huge hit, 'Diamonds' and it's just... Wow.

And what would a Carpool Karaoke be without James Corden wearing something ridiculous? In this case, he actually somehow manages to pull off Sia's infamous wig.
